Handshake Protocol

The Handshake Protocol is the initial phase of a secure communication session where two parties negotiate the parameters of their secure connection. During this process, the client and server agree on the version of the protocol, the cryptographic algorithms to be used, and the authentication methods.

In the financial domain, the handshake is critical for establishing a secure tunnel before any sensitive trading data is transmitted. It involves exchanging digital certificates to verify the identity of the trading platform and performing a key exchange to derive session-specific encryption keys.

This process ensures that both parties are legitimate and that the communication channel is resistant to tampering. The efficiency and security of the handshake protocol are vital for minimizing latency in trading environments while maintaining high security standards.

If the handshake fails or is compromised, the connection is aborted, preventing any potential exposure of financial information. The protocol must be resilient against various types of attacks, such as replay or man-in-the-middle, during the negotiation phase.

It serves as the foundation for all subsequent secure communication between the trading entities.
